I need schooling - old vs. new engines

To be brief.. High powered integrated computers analyzing every facet of engine management including timing, air fuel ratio, shift points and even ambient air temperature. That together with computer designed aluminum cylinder heads with variable camshafts and engine blocks and multi speed transmissions. As far as Im concerned, technology at its best. Chev-LS , Ford, Coyote, DODGE, Hemi. All great powerplants.
